Hose Assembly Flange Structure for Accurate Spring Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current hose assemblies for fluid systems in vehicles are prone to installation errors of support springs, which can lead to incorrect positioning and displacement, causing system failures and reduced vacuum resistance, resulting in hose collapse and operational issues.
Innovation Solution
The hose assembly features a support member with varying diameters and flange portions to ensure accurate installation and retention of the spring, preventing displacement and enhancing vacuum resistance by engaging the spring's ends with specific flange surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a spring is manually installed within the hose to provide support, then the hose gains vacuum resistance, but the installation process is prone to errors causing incorrect positioning
Solution Approach 1:
The hose is pre-formed with an expanded region and flange portions during manufacturing, creating a predetermined installation structure that guides the spring into the correct position. This preliminary preparation eliminates the need for manual positioning and ensures consistent, error-free installation.
Solution Approach 2:
The flange portions act as intermediary structures between the spring and the hose body, providing engagement surfaces that secure the spring in the correct position. These flange portions prevent incorrect installation by physically blocking misalignment and ensuring proper orientation.
2Stability of the object's composition
If the spring is installed within the hose to prevent collapsing, then the hose maintains structural integrity, but the spring may be displaced by fluid flow causing system failures
Solution Approach 1:
The expanded region and flange portions are pre-formed during hose manufacturing to create a dedicated retention structure. This preliminary action ensures the spring is captured in the correct position and prevents displacement by fluid flow throughout the hose's operational life.
Solution Approach 2:
The flange portions serve as intermediary retention structures that mechanically engage with the spring ends. These flange portions act as physical barriers that prevent the spring from being displaced by fluid pressure while still allowing the hose to flex and maintain structural integrity.
3Ease of operation
If a small expanded region with a lip portion is provided for spring capture, then the spring can be retained, but the spring is susceptible to movement and installation errors
Solution Approach 1:
The hose structure is segmented into distinct functional regions: a first portion for fluid flow, a second expanded portion for spring retention with flange portions, and a third portion for connection. This segmentation creates dedicated zones that improve both retention and positioning accuracy.
Solution Approach 2:
The flange portions are intermediary structures that extend from the expanded region to provide additional engagement surfaces. These flange portions enhance the retention mechanism by creating multiple contact points with the spring, preventing movement while maintaining ease of installation.

AI summary
A hose assembly includes a hose and a support member. The hose includes a first portion, a second portion and a third portion. The first portion defines a first diameter. The second portion defines a second diameter that is different from the first diameter. The third portion defines a third diameter that is different from the first diameter and the second diameter. A first flange portion is defined at an intersection of the first portion and the second portion. A second flange portion is defined at an intersection of the second portion and the third portion. The support member includes a first end portion and a second end portion. The first end portion is adapted to engage with the first flange portion. The second end portion is adapted to engage with the second flange portion.
